This invention relates to an internal combustion engine and has particularly to do with a combined counterbalance and speed governor construction.

It is an object of the present invention to provide a simple construction in an internal combustion engine for driving oil or scavenger pumpsand at the same time providing a speed governor control and a counterbalance arrangement for the crankshaft.

Another object is the design of a speed governor control within the confines of the present crankshaft and oil pump housing.

I For a more detailed understanding of the inventlon, reference may be had to the accompanying drawings illustrating a preferred embodiment of the invention in which like parts throughout the several views are designated by like numerals, and in which:

Fig. 1 illustrates a vertical section of an internal combustion engine showing the relationshipofthe parts, J

Fig. 2 is a vertical section of an engine showing a modified pump and governor construction.

In Fig. 1 a crankcase housing l supports a crankshaft i'l inbearings l2 and 13. A cylinder II, in which reciprocates piston it with connecting rod I6 is mounted on the crankcase. A cooling fan and flywheel I! rotates on the free end of the crankshaft passing air through housing I8 past the finned cylinder i4.

At-the working end of'the crankshaft II is a generator 20 having its rotor coupled suitably to the, shaft. 1 e

A toothed gear .25 is formed as a part of the throw of the crankshaft to engagea gear 28 mounted ona shaft 21 ,iournaled atthe bottom of housing l0. At the left end of shaft ZIis an oil pump 28 of standard construction. Formed on gear 28 are ofl-center axial projections '30 and 3| which serve as balance weights for the throw of the crankshaft. which it will be noticed is a" which bears against a spool 14 slidably mounted on shaft 21. The other leg of the governor arm serves as a centrifugal weight whichis thrown radially upon rotation of shaft 21.

Bearing against the other end of spool 34 is 6 Claims. (Cl. 123-108) 2 crankshaft I I while shaft 2! drives oil pump 28.

' At the same time excessive speed of the engine in this case a pump at each end. Sliding spool beyond a predetermined amount will tend to shift governor arm 33 and spool 34 to move lever 35 to a decelerating position.

In Fig. 2 a somewhat similar disclosure is shown having a single throw crankshaft 45, with'gea'r driving gear 41 and pump shaft 48 which has,

49 and throttle arm 50 are controlled by governor arm -5l pivoted onoff-center extension 52 of gear 41. An additional small counterweight 53 may be added if necessary to supplement ex, tension 52 and arm 5|. Housing 55 supports the usual cylinder 56 with piston 51 cooled by fan- Although I have illustrated but one form of my invention and have described in. detail but a single application thereof, it will be apparent to those skilled in the art to which my invention pertains, that various modifications and changes may be made therein without departing from the spirit of my invention or from the scope of the appended claims.

What I claim is;

1. In an internal combustion engine of the type having a crankshaft and a pump shaft driven from the crankshaft, a throttle control member,

a combined governor and counterbalancing unit 1 structure which comprises a governor member eccentrically mounted on said pump shaft and which is shiftable in response to rotation of said shafts, and means operably connecting said members to provide speed'control for said engine.

2. In an internal combustion engine, a crankshaft, a pump operating shaft mounted adjacent said crankshaft and driven thereby, a throttle control member, a combined unitary overnor and counterbalancing means which comprises a governor member eccentrically mounted on said pump shaft and operable in response to rotation of said shafts, and means comprising a sleeve .slidable on said pump shaft operably connecting said members to cause oneto move in response to the other to thuseil'ect governing action.

3. In an internal combustion engine, a pump operating shaft mounted adjacent said crankshaft in the same housing, said crankshaft having a single throw, a driving connection'between a throttle control lever II: pivoted on the houslog [I and arranged to rotate a shaft .38 to con trol the'throttle (not shown) of the engine.

said shafts, a throttle control member mounted in said housing, and means to serve as a throttle governor and counterbalance comprising a governor member mounted on said pump shaft D0- 'sitioned with opposed eccentricity to said crankshaft throw, and movable in proportion tothe governor and counterbalance comprising a governor member mounted on said pump shaft positioned with opposed eccentricity to said crankshaft throw, and movable in proportion to the rate of rotation of said shafts, and means comprising a sleeve slidable on said pump shaft operably connecting said members to cause one to move in response to the other to thus efiect governing action.

5. In an internal combustion engine, a pump operating shaft mounted parallel to said crankshaft-in the same housing, one or more pumps at the ends of said pump shaft, a gear for driving said pump shafts mounted between the ends thereof and meshing'with a gear formed on the throw of said crankshaft and arranged coaxial having an eccentric position opposed to the throw with, respect to the crankshaft axis, a throttle control member mounted in said housing, an offcenter axial projection on said pump shaft gear of said crankshaft, a. bell crank lever pivoted on said projection one end of which is axially offset from the pivot position to serve as a centrifugal weight, the other end being operatively connected to said throttle control member whereby the memher and the lever are mutually shiftable to furnish speed governing control.

6. In an internal combustion engine, a pump operating shaft mounted parallel to said crankshaft in the same housing, one or more pumps at the ends of said pump shaft, a gearfor driving said pump shafts mounted between the ends thereof and meshing with a gear formed on the throw of said crankshaft and arranged coaxial with respect to the crankshaft axis, a. throttle control member mounted in said housin an offcenter axial projection on said pump shaft gear (located between said gear and a pump) having an eccentric position opposed to the throw of said crankshaft, a bell crank lever pivoted on said projection one end of which is axially offset from the pivot position to serve as a centrifugal weight,

the other end being operativeli connected to said throttle control member whereby the member and the lever are mutually shiftable to furnish speed governing control.
